To all whom t may concern:

Be it known that I, GEORGE H.,GRAvEs, a citizen ofthe United States, and a resldent of the city of Chicago, county of Cook,

and State of Illinois,'have invented certain L new and useful Improvements in Fans, of

/ which the following is aA specification.

My invention relates to improvements in fans and has for its object the provision of improved coin controlled mechanism for throwing the fan into and out of operation.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed. I

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,- l A Figure 1 is a side view of a fan equipped with mechanism embodying my invention, Fig. 2, a face viewof the same, Fig. 3, a

central section through the base of the fanA as shown in. Fig. 2 and looking in the direcv"tion of the arrows 3-3, Fig. 4, a similar view looking in the direction of the arrows 4-4 on Fig. 2, Fig. 5, a section taken' on the A. line 5 5 of Fig. 3, Fig. 6, a section takeny on the line 6`6 of Fig. 3, and Fig. 7, a 'section taken on line 7--7 of Fig. 3.

The preferred vform of construction as illustrated in the' drawings comprises an ordinary electric fan 8 mounted to be operated by an-ordinary electric motor 9, said motor being supplied with current through an ordinary electric cord 10, as will be readily understood. A shaft 11 is connected by a .suitable reducing gearing inclosed in the housing 12 with the motor shaft, as will be readily understood. l Shaft llis connected with a longitudinally extensible shaft 13 by means of a universal joint 14, said shaft 13 being formed in two telescoping parts, the

louter part being provided with a longitudinal slot 15 and the inner part with a pin 16` slidably engaging said slot, said construc-l tion permitting of longitudinal extension of said shaft while transmitting rotatlon, as will be readily understood. This arrangement is provided to permit of oscillation of the'fan 8 in any direction while motor 9 is driving shaft 13. At its lower end shaft 13 1s connected by a universal joint 17 with the l upper end of a shaft 18- mountedin the top of ahollow base 19 which serves as a support for the fan as shown. Within the base 19, shaft 18 is arranged in coaxial alinernent with a shaft 18 which in turn carries al v l worm 20 meshing with a worm wheel 21 on a shaft 22 which Iin turn carries a worm 23 meshing with a worm wheel 24 fixed to the bottom of a centrally positioned vertical shaft 25 mounted in base 19 and in a bracket 26 therein. A clutch member ,27. is

fixed to the lower end of shaft 18 and co- 4 spring' 30 and is normally held from such engagement by means of a collar 31 .and a knife blade 32 engaging said collar. Knife blade 32 is carried by a disk 33 which is fixed 'on a shaft 34 normally held in the position shown in Fig. 5 by means of a spring i 35. The disk 33 also carries a switch 36 cooperating with electric. contacts 37 and 38, as shown. One wire of the cord 10 is broken and one broken end connected with the contact 37 and the other end with the contact 'l' 38 so as to forma break inthe motor circuit closable by switch 36, as willv be readily understood.l 3y this arrangement it willbe -observedythat clutches 27 and 28- are nor' mally held from engagement so as-to disconnect the motor 9 from the'mechanism in the base and the motoncircuit normally held broken so as to prevent operation of said motor, but that upon swinging of'disk 33 the knife blade 32 will be withdrawn and switch 36 placed in operative relation with con! tacts 37 and 38 to connectthe motor shaft with the sha/ft 18 and' close the motorcircuit simultaneously, thus causing shaft 25 to rotate but at a greatly reduced speed owing to the gearing disclosed. i

A. disk 40 is loosely mounted on shaft 25 and carries a clutch41 coperating with a Iclutch 42 having la, slot and pin connection' 43 with shaft 25, a spring 44 normally holding clutches 41 and 42 ln yielding engagement with each other. `The teeth A45 onv clutches 41 and 42 arel made V-shaped as. shown in Figs. 3- and 4 so .thatclutch 42 will normally drive clutch 41 and consequentlyl disk 40 but when rotation of either matically ride out of engagement with teeth 41 to permit rotation of either clutch memvber while the other remains stationary.

gearing .3,0

Thus, when clutch `member 42 is held from rotationlby the automatic locking action of the worm wheel 24 and worm 23, nevertheless the disk may be rotated, as will be readily understood. Disk 40 y'carries a pin 46 projecting downwardly therefrom and set in position to rest normally in a notch 47 in the periphery of disk 33. Disk 33 is also provided with another notch 48 in the periphery thereof adapted to be engaged by one arm 49 of a spring held lever, the other arm 50 thereof being set in normal contact with a pin 51 projecting upwardly from disk 40. By this arrangement, it will be.observed that by rotating disk 40 in a clock-hand-wise direction as shown in Fig. 5, the disk 33 will be rotated to cause knife blade 32 to disengage collar 31 and switch 36 to engage contacts 37 and 38 to close the motor circuit thus simultaneously connecting `shaft 18 with the motor shaft and at the same time starting the motor to rotate said shaft. 'llhe rotations of shaft 18 are communicated to disk 40 through the above described to cause return movement of disk 40. At the end of this return movement pin 51 contacts with arm 50 thus throwing arm 49 out of engagement ,with notch 48 and releasing disk 33' which,

under the influence of spring 35 is rotated to withdrawswitch 36 to break the motor circuit and throw knife' blade. 32 into en- Y gagement with collar 31 to disengage clutch I27 from clutch 28 and thus disconnect the motor from shaft.18. By disconnecting the motor from .shaft l18 the abrupt "stopping kofthe motor is avoided and the motor-permitted to spin under the influence lof its inertia without disturbing the adjustment of the arts connected therewith through `he .clutch 27. Another and smaller disk 52 is secured to shaft 25 above disk 40, saidd/isk 52 being provided with a plurality of notches 53 in the periphery thereof. An operating lever '54 is pivotally mounted on shaft 25, extends radially therefrom `and is provided with van .upturned out/er end 55 projecting throughfa segmental slot 56 in the top of base 19 to constitute a handle for operating said lever from the outside of said base. Registering slots 57 are formed in the top of base 19 and in lever y 54 and a [tl-shaped coin holder 58 is secured to the vbottom ofk said lever in' position to embrace' a coin inserted through said slots.

A vcoin guide 59 is arranged around coin holderj58 and is provided inits louter wall witha cam surface 60 adapted to engage the outer edge of a coin in coin holder 58 `upon swinging of lever 54 to the right whenbell crank with lever 54. rllhis rotation 'A While l have illustrated forcing the Vcoin to move .inwardly during the initial'motion of said lever. rlhe upper portion of-,coin holder 58 is notched to receive the downwardly turned `end61 of a slidablecatch member 62 mounted on lever 54, and normally held in its eXtreme outer position by means o f springy 63. `,'l`he inner ed of catch 62 is -provided ywith aY nose or shoulder 64 adapted to vengage notches 53 in' the periphery of disk 52. yBy this arrangement, upon insertion of a suitabley coin or token into coin\holder 58 through slots 57, said coin will be normally held in the outer portion of said coin holder infposition to strike the cam surface 60 and with its forward edge in contact with the downwardly turned end 61 of catch 62. Upon operative movement of lever54, the outer edgeof said coin will be engagedby cam surface 60 to force said coin inwardly. rll`his inward movement of the coin will force the catch 62 inwardly toengage the corresponding notch 53 and cause rotation of disk 52 of disk will cause simultaneous rotation of shaft 25 and consequently of disk 40 which, as explained above, will close the motor circuit and connect the motor with disk 40 to cause return.

The arrangement illustrated provides for the de osit' of ten coins, and in order to pref vent. t e depositof more coins, disk 52 is providedyvwith a downwardly extending pin 65 set to contact lwith an arm 66 on a shaft 67 normally held by means of a spring 68 with arm 66 in contact with a. stop pin 69., Shaft 67 also-carries 'an arm 70 which is arranged tov swing across thexb'ottom of coin holder 58 to prevent the complete insertion of a'coin therein. f The pin 65 is set to contact with arm 66 during the vlast movement of the diskj52 provided for, andthus swing arm 70 into position to prevent the insertion of another coin. -Y
